What Does 'using Namespace Std' Mean in C?

It is very simple.namespace gives you simply a space where you can declare/name variables without bothering about other developers. Lets take a live world example.

Suppose there is a Joshi family living in Madhya Pradesh. Now the family has three children, and they are brothers. These brothers decided that after marriage if anyone of us will have a female child we will name her Shardha.

Fortunately, all three brothers were enlightened with female babies. Everyone was happy and then they thought about the name and remembered what they decided in their childhood. So they named each child Shardha.

Now, since the family was joint so it was getting tough to call one when three of children are together. The children were intelligent so they device one solution i.e.

NAMESPACE. They proposed that they will add their fathers name after their name so it will be easy for others to call any one of them individually. I hope you got the namespace concept here after reading the para above.

Since std stands for standard, hence std has all the standard libraries available under std namespace. If you want to create the same functions/variables as there are in the standard library you can do so by creating your own namespace and calling them using your namespace. e.

g. You can include both the namespaces in your programusing namespace std;using namespace yourownnamespace;and then you can use them as per your use casestd::coutyourownnamespace::cout

What is the difference between class and object in OOP?

An object is a identifiable entity with some particular characteristics and behaviour.Class is a collection of similar objects having similar characteristics and behaviour.For exampleAssume yourself as an object with your height, weight as your characteristics while your ability to talk, walk and listen as your behaviour.

Comparing yourself from a group containing human beings. Human beings too have some height and weight. They can talk, walk and listen.

But each person has some unique properties. Thus human beings referred to as class while particular person as objects with some particular characteristics and behaviour.In Java , programming is performed with classes and objects as their centre.

Various classes are constructed within which objects are declared which perform various functions which the program wants to perform. For example you want to write a program to find the area , perimeter/circumference of different two dimensional figures.Here two dimensional figures is class while different figures like square, rectangle and circle will be it's objects having various functions like area and perimeter and properties like edges and so on but they resemble to same class.

Thus we can say class represent a group of objects sharing common properties and object can be defined as entity that has some unique properties that distinguish itself from others. I am ending this long answer of this simple by giving example of vehicles as class having property to transport people and cars and vans as objects which have some unique properties like their shape which distinguish itself from others in the same class.Thank you for reading

When you pass someone on the street, do you like saying u201cHiu201d to people or would you prefer to stay silent?

Do you like it when people say u201cHellou201d to you or do you prefer that they stay silent?

Whether I say hi to passers by depends on different and varied, changing factors. Sometimes my mood, where/what social environment Im in or they are in, what kind of mood they might vibe they are in, etc.

I personally am a somewhat relaxed person, I ENJOY relating to and/or acknowledging passers by for the most part based on afore mentioned filtering. If not a verbal hi, I dont mind initiating eye contact and a nod. Doing so helps ME feel connected, common man-all here for same purpose kind of thinking and feeling.

Regardless of social status, personalities or any other differences, for that ONE moment/second, we are the same and a humanistic acknowledgement levels us ALL AS people and humanseach w/our own path and lives. Do I prefer they say hello to me? Definitely!

IF Ive passed them w/o my initiating and THEY had, Ill go so far as to say Oh! Im so sorry; how are YOU? MY thinking IS we ARE ALL HERE!

Earning $, progressing n achieving, etc etc are things we cant take with us. MY thinking IS while were here, what can we do to make a difference. How many peoples lives can we touch-or theirs OURS!

What IS your fulfillment? WHO KNOWS WHAT can come from and/or because we made that eye contact and let another person KNOW we SEE them? Or, them, us?

And, I think that way about ALL life to include animals, little kids, elderly. They ALL MATTER! And, I HOPE I do too.

But, if ppl dont initiateI dont chase them down to rattle their cagesI keep thinking if I KEEP initiatingmaybe it will become contagious. Whats wrong w/making life FEEL GOOD, eh? :)

How normal is it for 13 year olds to make out?

Itu2019s perfectly normal and healthy. At 13, most kids are already feeling urges to experiment with themselves and to try to date someone. Most 13 year olds have a crush, and thatu2019s fine.

Itu2019s good if kids from age 12 and up start dating and kissing people (their age), because it helps them to learn how to act around someone theyu2019re attracted to. I hope that I get some experience in while Iu2019m still a teenager, because I know I would benefit from it when Iu2019m an adult. Iu2019m in no rush to get a girlfriend/boyfriend, but I would like to have one before Iu2019m done growing up, so I know a little bit more about what Iu2019m doing when Iu2019m older.

Prohibiting your child from dating or kissing people will not stop them. In fact, it will encourage them to do so. The reason itu2019s bad parenting to prohibit your child from dating but good parenting to encourage them is that if you encourage them to do it at home or in safe places, with good people, thereu2019s a much smaller chance theyu2019ll end up in a bad relationship.

I would definitely allow my 13 year old to date people and to make out with them. I would allow them to date people of the same gender, and I would allow them to talk about anything with someone theyu2019re dating, including sex. I wouldnu2019t want them having sex until theyu2019re 14 or 15, but so long as I encourage them and create a safe, supportive environment for them, theyu2019ll probably take my advice and wait a year or two

Is web development a dying career?

Let me throw in my $0.02 worth -NO absolutely not.Can I go and build a site on Wix?

A: Sure you can! Is it possible that it will look just like someone elses ? MOST DEFINITELY!

See - this is the issue wit cookie cutter site builders and even with some CMS - eventually you are going to see some one elses site that looks nearly identical to yours. Solution? BUILD A CUSTOM SITE!

As others have pointed out - emerging tech is going to always require a programmer to create sites with it - eventually some CMS or Site builder will find a way to implement a drag and drop, cookie cutter version of the tech - but by the time they do - NEW tech will be out! This is WHY it is important to stay on top of emerging tech - and continue your education for as long as you are in the business.Eventually - people are going to want to re-vamp their custom sites - if they werent built in a CMS or builder, that only leaves the programmer to come in and fix or re-vamp it.

As a side note - if someone builds a site on Wix - guess what it STAYS on Wix! No corporation is going to want to have their stuff hosted on Wix (or any other cookie cutter site for that matter). https://support.
